GROCO BP-1 Poly Basket - 1.9" x 5.2"

The GROCO BP-1 Poly Basket is a replacement strainer basket engineered for saltwater intake systems and marine fluid filtration applications. Manufactured from corrosion-resistant polyethylene, this 1.9" x 5.2" basket replaces worn or damaged originals in GROCO's ARG-500, ARG-755, and SA-500 series strainers. The improved handle design provides secure grip and easier removal, critical when servicing systems in confined engine spaces or during emergency maintenance.

GROCO poly baskets resist the corrosive effects of saltwater environments where traditional metal strainers degrade rapidly. The polyethylene construction prevents electrolytic corrosion that compromises steel baskets, extending service life and reducing unplanned downtime. The ergonomic handle ensures quick access during routine strainer cleaning—a maintenance task performed frequently on cruising vessels and commercial marine systems to prevent blockage and maintain engine cooling efficiency. Compatibility with multiple GROCO models makes this a standard spare part for boat owners and marine technicians maintaining seawater systems.

This basket is essential for any vessel relying on raw-water cooling or seacock strainers. Whether performing routine maintenance on a cruising sailboat, managing a fishing vessel's intake system, or servicing a yacht's engine cooling circuit, having replacement baskets on hand prevents operational interruptions. The compact dimensions allow storage in standard locker spaces aboard ship. This GROCO BP-1 model has become a trusted spare for marine engineers and boat maintenance crews who depend on reliable, corrosion-proof filtration components.
